Stuart Geiger has demonstrated that it is possible to transmit simple ping requests across two computers using people playing xylophones. Throughput is roughly 1 baud, when the participants don't make any mistakes, or get bored and wander off. The OSI encapsulated model of networking makes this project doable, allowing humans to be inserted at Layer 1, the physical layer. Vint Cerf wasn't kidding when he used to say, "IP on Everything.""
